AI: The Wishing Lipstick

Softly, the stranger whispered into Jon's stone, "I wish this stone and only this stone would turn into a tube of red lipstick that would only grant wishes to the people who have applied it to their lips." There was a flash and the stranger was suddenly holding a tube of red lipstick. He then placed the object down at Jon's bedside. As he was about to leave, the stranger turned back with a second thought. Pulling his own stone from his pocket, the stranger added, "I wish that once those people have removed the lipstick from their lips, they can no longer make wishes until they apply the lipstick to their lips again." He wanted to make sure that they'd have to be *wearing* the lipstick to make wishes. With that, the stranger left, as silently as he had come.
